Normal values of transfer factor and transfer coefficients in healthy males and females
Abstract:
A population study was performed to obtain local normal values of the transfer factor for a respiratory laboratory providing a routine hospital service. Statistical analysis of the results obtained showed similar results to those of previous investigators for the transfer factor and alveolar volume. The transfer factor was found to be dependent on height, age and sex, while the alveolar volume depended only upon height and sex. Unlike previous investigations, however, the present study showed that the transfer coefficient was the same for women as for men and was related solely to age.

Factors Affecting Erythropoiesis
Several factors influence the erythrocyte production rate, with tissue oxygen level being among the most critical. Intense exercise or high altitudes can cause tissue hypoxia, which triggers the kidneys to release more erythropoietin (EPO) into the bloodstream.
